Question

the president can force congress to meet during an emergency. which arrow on the diagram stands for this check on legislative power?

Explanation:

The question is about the system of checks and balances in the US government, specifically the executive (president) checking the legislative (Congress) power by calling a special session. In the diagram, the arrow from "Executive" to "Legislative" (the one going from the Executive circle to the Legislative circle) represents this check, as it shows the executive's action affecting the legislative branch.

Answer:

The arrow from the "Executive" circle to the "Legislative" circle (the green arrow directed from Executive to Legislative) stands for this check on legislative power.
